Title: XCode 5 refactor

Since this is an iOS 7 widget, you can assume developer use will be in XCode 5 or later. Did some general code cleanup and refactoring with that in mind.

Overview:
- moved private ivars into internal interface
- removed delegate setter that was performing behavior that is already the default
- changed properties to *strong* rather than *retain* since compile with ARC
- made class wide constants conform to Objective-C stytle
- moved dangling buttonHeight and buttonSpacerHeight to ivars
- removed underscored ivar access in favor of explicit self referencing
- changed all ivar referencing explicit to self
- changed butonTitles to NSArray from NSMutableArray since mutability not required (or desired)
